Tuʻi Tonga Empire
According to Tongan tradition, the line of sacred kings called Tuʻi Tonga began around 950 with ʻAhoʻeitu, son of the sky god Tangaloa and a mortal woman. From Tongatapu, the Tuʻi Tonga built a maritime chiefdom whose influence, through voyaging canoes, marriage alliances and tribute, extended at its height in the 12th and 13th centuries across Samoa, ʻUvea (Wallis), Futuna and parts of Fiji.
The royal centre at Muʻa has great stone-faced tombs called langi, and the Haʻamonga ʻa Maui trilithon is attributed to the king Tuʻitātui. After several Tuʻi Tonga were assassinated, around the 15th century they handed political power to a new line, the Tuʻi Haʻatakalaua, and later the Tuʻi Kanokupolu, keeping a sacred role. The title lapsed when Laufilitonga died in 1865, as George Tupou I unified Tonga as a modern kingdom.
